enIntended useThe STABILA LAX 300 G is an easy to use crossed line and plumb line laser. This unit is self-levelling through a range of ± 4.5° and allows you to work accurately on the horizontal and vertical green laser lines.Read the User Manual along with the illustrated portion. Follow the general instructions on the handling, care and maintenance of the instrument. Observe the safety instructions on laser beams.If you still have questions after reading through the operating instructions, you can obtain advice by telephone: 0049 / 63 46 / 3 09 - 0

enMain applications:Operating modesThe LAX 300 G can be used in 2 operating modes:1. as a self-levelling line laser 2. as a laser instrument for marking

+ plumb line laser applications without the levelling function

Operating mode with self-levellingA laser line can be selected in this mode.

Commissioning The instrument is switched on with the on/off switch (1b). Horizontal and vertical laser lines and the plumb line points appear after switching on.The laser will automatically level itself.

Setting the type of line:The vertical and horizontal laser lines with the plumb line point and the cross laser line can be set after each other by pressing the selector switch (1a).The laser will flash if the inclination is too great !laser beam flashing-> The unit is inclined too much

+ is outside the self-levelling range + the laser cannot level itself automatically

Operating mode without levelling function:The on/off switch (1b) is switched off. In this mode the LAX 300 G is only switched on or off with the selector switch (1a).

Plumb line function mode The foot can be extended in order to improve the visibility of the lower plumb line point. The LAX 300 G is positioned and switched on ( switch 1b ). The laser down beam is aligned as required to the object or a mark. Mark the position of the up laser beam on the ceiling. The laser lines are always switched on at the same time as the plumb line laser points.Always ensure that the centre of the laser line is marked !

Checking the calibrationLAX 300 G crossed line and plumb line laser is designed for use on the construction sites and left our factory perfectly adjusted. As with any precision instrument, however, its calibration must be regularly checked. The unit should be checked before starting any new tasks, particularly when the unit has been exposed to strong vibrations.

enHorizontal checking1. Horizontal checking - Line levelTwo parallel wall surfaces at least 5m /16‘5“ apart are required for thehorizontal check.1. Place the LAX 300 G on a smooth surface or on a tripod at a distance of 50 mm

to 75 mm in front of wall A and with the front side pointing towards the wall 2. Switch the unit on (1b).3. Mark the position of the visible laser line cross on the wall A (point 1).4. Turn the complete unit 180° without altering the height of the laser.5. Mark the position of the visible laser line cross on the wall B (point 2).6. Now move the unit directly in front of wall B.7. Set the unit‘s height so that the laser dot‘s height matches that of point 2.8. Without changing the height of the laser, rotate it 180° to place the beam

near the mark on the first wall (step 3 / point 1 ).

The following applies for the differences :

Δ ges 1 = Δ 1 - Δ 2 < ± 2mm 5/64“Δ ges 2 = Δ 3 - Δ 2 < ± 2mm 5/64“

When calculating, always take note of the preceding prefix !

2. Horizontal checking - inclination of the laser lineCheck the laser line for inclination and perfectly straight projection1. Mark three points (1, 2 and 3) on the floor at a distance of 5 m /16’5”

from each other; the points must be in a perfectly straight line.2. Position the laser at distance S = 5 m / 16‘5“ from the line and exactly

in front of the middle point you marked = position X3. Switch the unit on.4. Measure the height of the laser line at the points. Measurements X1 - X35. Reposition the instrument.6. Position the laser at distance S = 5 m / 16‘5“ from the line and exactly in

front of the middle point you marked = position Y7. Measure the height of the laser line at the points. Measurements Y1-Y3∆1 = X1 - Y1 ∆2 = X2 - Y2 ∆3 = X3 - Y3

Measure the vertical distance between point 1 and point 3. The difference must not be greater than :

enVertical checkYou must create a reference to perform this test. Fasten a plumbline near to the wall. The laser unit should now be set up in front of this reference mark(distance Y) and the vertical laser line compared with it.The discrepancy between the centre of the laser line and the reference mark should be no greater than 1 mm ( 3/64” ) over a length of 2 m ( 8 ft ). Checking plumblining1. Switch the unit on2. Place the laser so that its down beam is over a reference mark on the floor.3. Locate the position of the up beam on the ceiling and make a mark.4. Rotate the laser 180° and realign the down beam over the reference mark

on the floor.5. Locate the position of the up beam on the ceiling and make a mark.6.Measure the difference D between the two marks on the ceiling, which will be

twice the actual error. The difference may not be greater than: 3 mm in 5 m (1/8“ in 16‘5“).
